:terminant No. 89,741, dated Alira/4., 1869. l

Be it known that' I, ADDISON DAVIS, of Boston,

in thecounty of Suffolk, and `State of Massachusetts,

have invented an` Improvement in Sash-Supporters;

and 'I do hereby declare that the following, taken in `connection with the drawings which accompany and form part of ,this specification, is a description of my. invention sufficient to enable those skilled in the art to pi'tmtiseit.`

United States- LettersPatent, No. 83,697, were granted to ine November 3,1868, for an improvement in sash-supporting mechanism, the invention shown in such patent being designed particularly for use .in con--v nection with the windows ofA r`ai1way-carriages, and con-V `rattling-movement of it.

My-present invention relates to amodicati-on of my said patented mechanism, the improvement consisting in combining a pendent stop, with an incline,

at the endof a vertical rod,.worked in one direction by the finger-lever, and in the other direction, by the spring, the stop lbeing normally pressed outward, into l'some-pue of the notches of the bead, by the action of the spring upon'the incline, andfalling back ont of engagement with the notch, (by gravity,. or by the action'of the risers of the notches,) when the incline 'lhe drawings represent a wlndowiframe and sash embodying the improvement. l

As in my aforesaid patent, the sash is made somewhat thinnerthan therunning-space between the beads o d, so' that it may rise and'fall very easily.

Each or eitherbeadro, on its inner surface, is provided vvithaseries oinotches,- e, with which engages the sliding,stop,` f. L Y This stop f is, at the end of an arm, g,`hung pendent V Th'e Schedule referred to in these Letters Patent 'and making part of the same. Y

from a plate, h, fixed upon the'inner surface of the stile,thestop swinging freely upon the pin i, such pin being preferably so disposed as to cause the stop to `The arm g is recessed on, its inner side, and into this recess projects the point,l or end k, of an incline, or sliding dog,\l,. fixed. to, or forming. the upper end lprojecting from the plate h.

The lowergend of the slide-rod is connected to the outer end ofvan arm, o, on one end of a horizontal rocker-shaft, p, (preferably journalled within, or runthumb, or 4finger-piece, s, projecting .from the rockershaft,` at the centre of the sash-rail, this shankworking'in a verticalslot, t, lmade through a plate, n, and into the sash-bar.

Around the rod m is ia coiled spring, o, the stress of which presses the rod down, one end of the spring bearing against the guide n, and the opposite end against .a pin, projecting through the rod. The'operation of the stop will be readily understood. When the thumb-piece s is pressed up, the rod m is thereby raised, and the point of 'the incline, or dog Z, is pushed up, allowing the stop toV fall back into the hollow part Vof the dog. The sash may now be readilyraised or lowered, so long as the thumb-piece is kept pressed up towards a projection, w, at the topV of the sash-rail. But as soon as the thumb-piecev is released, the spring throws down theincline, and the inclinepresses the stop out into the notch opposite to which it happens to be, and vthe sash is thereby n'Xed in position, the pressure of the stop against the back of the n otch (caused by the gaging with the bead-notches o, with the incline, or

dog l, slide-rod m, and spring `o, arranged to operate together, substantially as described.
